They are actually elements so that is pure substances. Mixtures are more than one type of element that are in the same space but not touching. Compounds are like mixtures but they are touching.
Examples of substances that are elements include hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon
Matter is classified as mixtures and substances. Mixtures are made up of two or more different substances that are physically combined, such as saltwater. Substances consist of only one type of atom or molecule, like elements (e.g. gold) and compounds (e.g. water).
whyMatter can be broken down into Pure Substances and Mixtures. Mixtures can't be broken down by anything, however Pure Substances break down to Elements and Compounds.The mixtures whether it is homogenous or heterogoneous can NOT be broken down and be observed because it is a chemical change not a physical change
This is a very hard question! Does anybody else know?
pure substance all elements and compounds like gold, hydrogen, water, methane etc. impure substance mixtures of different substances like milk, soil, sea water, minerals etc
Hydrogen, Helium, Carbon, Gold, Silver, Oxygen
Substances: water, salt (sodium chloride), oxygen, gold, and diamond. Mixtures: air, saltwater, stainless steel, trail mix, and concrete.
Examples of substances that are elements include hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon
Gold, Silver, Oxygen, and Hydrogen are not compounds because they are all elements.Sources- Science book. ^_^P.S- This better have helped!

a mixture is something that has just been mixed together with something else and has not been chemically bonded however and element is something in its simplest form like gold, sodium, helium etc
water, methane, oxygen, silver, gold.
